Letters Patent No. 64,258, dated April 30, 1867.

IMPROVED AMALGAMATOR.

TO ALL WHOM ITAMAY CONCERN Beit known that we, ANTHONY J. SENATZ and GEORGE W. KNOWLTON, of v-the city of' Sacramento, in the county of Sacramento, and State of California, hav-e invented a new and improved Mode of Amalgamating and Separating Gold, Silver, and other Precious Metals from the rock, sand, earth, or other base materials with'. which they may be combined in their native state; and we do hereby declare that the following is a. full and exact description thereof` reference being had to the accompanying drawings, and to the letters of reference marked thereon. v

The nature ofsour invention consists in providing twopans with copper' bottoms, raised one above the-other, and connecting by a rod of'iron with slots therein, on each side of the pans, and a vibrating spring at the outside o'f the pans, the pans running on groov'ed rails, and having pins connected with the slots on each side. The two pans are also connected by pipes leading from the top pan, for the water and sand to run into the lowerpfn, wherein there are discharge pipes provided. We also claim a series of riiiles, made of wood, brass, iron, or other suitable metals, and attached to plates, which are'to be attached to,stationary upright posts on each side of the frame, and having the riil'les facing downwards on the inside of the pans.

v'lo enable others skilled in the art to make and use our invention, we will proceed to Ldescribe its construction and operation, reference being had to the accompanying drawings, making a part of this specification, in whichi Plate 1 is a perspective 4view'ofthe whole machine complete, with one rile-bed out, which is`shown bottom side up at plate Q and having only a portion of the staples on, and four ritlle pipes. The object of these pipes is tovcarry the quicksilver to the bottom'ofthe pans, as at the slot in fig. 2, plate 3. Fig. 3, on top of saine plate, showsvthe opening into this slot for charge. A l

Plate 4 is a drawing, on an enlarged scale, of the staples used on the rille-beds.. These beds may be made of woodor metal, and if oi' wood the staples may b e made of wire, of suitable size, driven into it; or if made of cast ilron, the pins or staples may be cast with' it. 'lvhe pans, as represented in plate 1, iig. 6, are lined with copper plate, and made of an oblong form, with ends turning upwards'.-

` Te construct a frame, as represented in plate 1, of any convenient size to contain the copper-bottomed pans moving therein on slides, by means of the power applied to the iron bars or rods, with slots attached to the sides of 'these pans with pins. At the top of the posts of the frame we place the riile-bed, secured by mortise and tenon, as represented in plate 1igs.` 1, 2, 3, 4. These figures represent notches to receive the riiie-bed facing downwards, and corresponding with thc inverted riiilc-bed, represented in plate 2, lig. 5.

Plate 1, figure 5, is the rille-bed in position.

Plate 1, figured, are the pans, liped with copper, and having the ends turned upwards.

Plate 1, ligure 7, is 'a rubber mspiral spring. f

Plate 1, figure 8, are the cohntcting rods required for driving. in thc ends of which -are slots.

Plate 1, figure 9, is the main shaft with crank.

Piate 1, figurelO, is the driving power. i

Plate 1, figure 11, are discharge pipes.

Plate 1, figure 15, are slides on which the pans movc.

When in operation, thelsand; earth, or other baie material with which the precions metalmay be connected, is thrown into the open end of the copper-bottomed pan, uppermost in theframe. which is supplied witha suiicient stream of water, and. put in motion'by the power, plate 1, iig. 10, applied on the shaft with crank, as at iig. 9, connecting with the iron rods with slots in the'ends, as at fig. 8. By this motion, the water and sand, earth, rock, Ste., in the pans are moved backwards and forwards with a ripple, produced bythe turned-up ends of the pans; and are also thrown upwards against the rillles in the stationary beds facing downwards, untilthey are sailiciently washed to escape through the discharge pipes, as at fig. 1 1, plate 1. The gold or other precious metal amalgamates with the quicksilver rcceivedinto the bottom o f the pans through the slots in the rile-beds', as

represented in plate 2, g. 12, and in plate 3, g. 3, the undulating motion being secured by the slots in the iron bars. l

What We claim as our invention, and desi-re to secure by Letters Patent, is-

The copper-bottomcd pans, with the iron rods or hairs und slots in the end, fastened to the sides ofthe pans with pins, and by means of which rods or bars the pans are f cned together, and nn undulating motion is secured for the waiter and earth, which are dashed inwards against the stationary riiics, whereby the earth or sand is prevented from becoming solid. l F W'e also chr-ini, as a part of the sumo nmchinc, the turnod-up ends of'nhese pans, and the stationary riicbeds connected with the pans; uli of said parts being the machine in combination, which will produce the intended effect.
